UNITED STATES PATENT OFFICE.

CHARLES H. BARR, OF FITTSBURG, PENNSYLVANIA, ASSIGNOR TO THOMAS B. KERR,OF SAME PLACE.

WIRE FENCE.

SPECIFICATION forming part of Letters Patent No. 289,207, dated November27, 1883.

' Application filed May 21, 1883. (N model.)

To all whom it may concern.-

Be it known that I, CHARLES H. BARR, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Wire Fences; and I do hereby declare the following to bea full, clear, and exact description thereof.

My invention relates to that class of wire fences in which the wires areprovided with plates at proper intervals for the purpose of renderingthe fence visible, and thereby warning cattle of the presence of thebarrier. When the tablets or wires are provided with barbs, thevisibility of the fence reduces the liability of animals being injuredby the barbs.

To enable others skilled in the art toinake and use my invention, I willnow describe it by reference to the accompanying drawings, in which- IFigure l is a side view of one form of my improvement. Fig. 2 is a planview. Figs. 3and 4 are perspective views of modifications.

Referring to Figs. 1 and 2, the plate or tablet ais made of sheet metal,and is provided with notches b in two opposite edges. The other edgesare provided with barbs 0, form ed by cutting the plate diagonally andturning the points outward. The plate is inserted between thestrand-wires d, and the latter are twisted up close into the notches b.This secures the plate firmly in place and guards against its lateraldislodgment.

In Fig. 3 I show a plate in which the notches b are formed by a diagonalcut, and the point thus severed turned out to act as a barb, c. 'InFig.4. barbs 0" are formed by bisecting the corners and turning the pointsthus formed in any desired direction.

The advantages of my invention consist in the security with which theplates are fastened 0 in the wires, the lightness and durability of theplates, and the strength and cheapness of the barbs, they being formedon and constituting a part of the plate.

A fence-wire provided with these plates can be rolled up in the samemanner as barbed wire is usually put up for sale.

I am aware that pointed guard-plates, knifeedged guard-pl ates notchedto receive the wire, and barb-edged guard-pickets have heretofore beencombined with wire-cable fencing, and do not hreinbroadly claim suchdevices; but, in the first place, the guard-plates secured by thestrands of the cable, as heretofore used, were not of acharacter topresent an effective barbed 5 5 surface and at the same time act asguardplates; and, secondly, the guard-pickets, while devoid of saiddisadvantages, could only be used with the several wires of a section offencing, and could not be secured to the wire cable when manufactured.Therefore What I claim as my invention, and desire to secure by LettersPatent, is

The combined guard-plate and barb, consisting of a flat plate notched ontwo of its 6 edges and having its remaining edges cut diagonally, andthe points thus formed bent out ward to form barbs, substantially as andfor the purposes specified.

In testimony whereof I have hereunto set my hand this 19th day of May,A. D. 1883.

CHARLES H. BARR.
